WARNING

NEPHROGENIC SYSTEMIC FIBROSIS

Gadolinium-based contrast agents (GBCAs) increase the risk for NSF among patients with impaired elimination of the drugs. Avoid use of GBCAs in these patients unless the diagnostic information is essential and not available with non-contrasted MRI or other modalities. NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and internal organs.

  • Do not administer OptiMARK to patients with:
    • chronic, severe kidney disease (GFR < 30 mL/min/1.73m²), or
  • Screen patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (e.g. age > 60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing
  • Do not exceed the recommended OptiMARK dose and allow a sufficient period of time for elimination of the drug from the body prior to any re-administration [see WARNINGS AND PRECAUTIONS]

DRUG DESCRIPTION

OptiMARK (gadoversetamide) injection is a nonionic gadolinium chelate of diethylenetriamine pentaacetic acid bismethoxyethylamide (gadoversetamide), for intravenous injection.

OptiMARK injection is provided as a sterile, preservative-free, nonpyrogenic, clear, and colorless to pale yellow, aqueous solution of gadoversetamide. Each mL of OptiMARK contains 330.9 mg of gadoversetamide (0.5 millimole), 28.4 mg of calcium versetamide sodium (0.05 millimole), 0.7 mg calcium chloride dihydrate (0.005 millimole), and water for injection. Sodium hydroxide and/or hydrochloric acid may have been added for pH adjustment.

Gadoversetamide is designated chemically as [8, 11-bis(carboxymethyl)-14-[2-[(2-methoxyethyl)am in o] -2ox oe th yl] -6-ox o-2-ox a-5, 8, 1 1, 14-t etr aa za h exa dec an-16-oato(3-)] gadolinium with a formula weight of 661.77 g/mol and empirical formula of C20H34N5O10Gd. The structural formula of gadoversetamide in aqueous solution is:

Viscosity (cP) @ 20°C 3.1
@ 37°C 2.0
Density (g/mL) @ 25°C 1.160

OptiMARK has an osmolality of approximately 3.9 times that of plasma (285 mOsm/kg water) and is hypertonic under conditions of use.
